Integrated energy-saving vacuum pumps GEM
presentation
The GEM series vacuum pumps integrate Coval's Twintech™ technology, a combination of two innovative technologies: IPR (intelligent pressure regulation) and IVC (integrated vacuum control). GEM series pumps provide an "all-in-one" solution
integrating all the required functions, such as pressure regulation, controls, valves, vacuum switch and silencer in a single compact module. The M12 connection radically simplifies installation and usage. GEM series pumps are available with two levels of vacuum, 60% and 90%, and five nozzle diameters (1.2 ; 1.5 ; 2.0 ; 2.5 et 3.0 mm).

IVC : Integrated Vacuum Control
Integrated solenoid pilots
Traditional single or multi stage vacuum pump must be equipped with additional peripheral modules necessary for its functioning:
solenoid-pilots, valve and electronic circuit, supply pressure regulator, vacuum switch and blow-off valve, which lead to increased dimensions, weight, complex wiring and additional cost of the overall vacuum system. The patented ivc technology of COVAL allows the
integration of all necessary functions into a single compact and light weight module. The installation is drastically simplified: no need to select, order and install additional peripheral modules as it comes in a ready to use plug and play format.



Even the multi stage models of traditional vacuum pumps are noisy and consume substantial amounts of compressed air. COVAL
resolves this problem with the ipr technology. The internal intelligence of the GEM vacuum pumps combine permanently the function of the integrated pressure regulation system to the venturi profile whatever be the pressure in the air network. The unique combination of the pressure regulator and venturi reduces both the sound level and the energy consumption significantly.
